In the next Prime Minister Infinity – U.K. release, there will be a new Relations screen (it is actually a tab on the Players Info screen). Here you can see it at the start of a 2017 campaign.
You can see a new number, ‘Distance’, which is the platform distance between yourself and the other player, expressed as a percentage of the maximum possible distance (so, if every one of your issue positions were diametrically opposite, that would be 100%). This value is also displayed visually as the distance from a starting point on a line, above the number.
This new screen will also be included in President Infinity and Congress Infinity.
